We had Celestial Solar complete the installation of our solar unit at the end of May 2025. The whole team did an amazing job from start to finish - design, county approvals, utility company, SRECS, installation, monitoring system, and even helped me with a state grant program. Jim (owner) was always available and the whole team was super helpful and communicative. We had ZERO issues - so smooth. Our system was designed for 100% offset and we have out produced usage every day since install. The panels look great. We couldn't be happier with our choice. I received over ten different estimates from the leading solar companies and not only was Celestial competitive with the most competitive prices, but offered higher quality materials and completes all the work in house. Highly recommend.

We met with Jim Reilly, of Celestial Solar Solutions in the fall of 2024, when we were getting bids for a solar installation. Jim impressed us right off the bat with his years of experience, clear presentation, and professional manner. After we agreed to go with Celestial Solar Solutions, Jim began the process of getting the permits we needed to install solar panels on our house over the winter of 2025. He. was very open to my suggestions for modifying his initial design and we went back-and-forth a few times before we got what in my view was the optimal design, with maximum coverage on our south-facing roof planes. Celestial Solar Solutions offers a winter installation discount. However, because the winter was harsher than expected, the installation was delayed until April, yet the company still honored the winter discount. Once the permits were approved and the weather warmed up, Jim’s employees began the installation process from finalizing the exact layout of the panels on the roof to assessing the capacity of our fuse box and electrical connections. On the day of the installation, about eight installers and electricians arrived and got the job done before the day’s end. The crew was efficient, neat, and professional. Several weeks later, our system was up and running. In late spring, Jim also alerted us to the Maryland energy administration’s solar access program. We applied and were awarded a rebate of over $5000; that’s in addition to the federal solar rebate we are already getting. Our entire experience with Celestial Solar Solutions has been top-notch. Their office support has been wonderful as well. We highly recommend the company to anyone considering a solar installation.

Celestial Solar's estimate was the best one and Jim was great to work with. Prompt communication through the entire process and the work was completed on time. I didn't need to do anything and the installed panels look great.

I recently had a solar system installed by Celestial Solar Innovations and couldn't be happier with the experience. From the start, Jim was fantastic to work with—professional, knowledgeable, and clearly passionate about what he does. He took the time to walk me through every step of the process, explained the technology in detail, and answered all my questions thoroughly and quickly. I really appreciated his transparency and how he shared insights from past projects, clearly demonstrating a commitment to continuous improvement. The installation crew was just as impressive—friendly, professional, and attentive to my preferences. They took the time to talk with me during the install and followed my requests for conduit placement exactly. The equipment they use is top-notch and looks great on my home. Best of all, they managed all the coordination with my HOA, the power company and SRECtrade, so I didn’t have to lift a finger. While I received similar quotes from larger regional installers, I'm so glad I chose this local company. The personal attention and quality of work really stood out. I’ve already recommended Celestial Solar to friends and neighbors and will continue to do so. Highly recommended!

Exceptional Communication and Professionalism! We recently had the pleasure of working with Celestial Solar for the installation of solar panels at our facility, and we couldn't be more satisfied with the experience. From start to finish, their team demonstrated outstanding professionalism, keeping us informed every step of the way. Their communication was top-notch—whether it was project timelines, permitting updates, or answering our questions, they ensured we were always in the loop. The installation process was seamless, with their crew working efficiently and respectfully on our property. They completed the project on schedule and left the site in immaculate condition. It's clear that Celestial Solar takes pride in their work and values their customers. If you're considering solar energy, I highly recommend them for their reliability, expertise, and commitment to excellent service.

We were first referred to Celestial Solar Innovations by a neighbor who had a system installed 7+ years ago and spoke very highly of them. After meeting with Jim for the first time, we understood why. Celestial Solar’s excellent customer service starts the moment you interact with the company, and it is evident that Jim’s personal commitment and vision as a business-owner permeates throughout this entire team. Jim briefly informed us of his story to his eventual founding of Celestial Solar and why, at this time, he only focuses on providing the best service to his customers in Maryland. He presented a detailed qualifications package, and a proposal based on previously requested information that contained all the pertinent information needed for us to make an informed decision. He patiently answered our many questions and provided expert feedback. As the discussion turned to acquisition of an EV, Jim adjusted the proposal to account for all downstream impacts related to future production and consumption including upgrades needed to the electric panel for EV charging. Upon execution of the proposal and agreements, Jim and his team provided high level communication regarding the final survey/design and were very responsive to any questions we had along the way. While it is nice for a plan to go off without a hitch, Jim and the Celestial team showed that they continue to shine when “hitches” do arise outside of their control (e.g. delays related to permitting and timing of the final inspection). Celestial does what it takes to be there on your behalf every step of the way. It is a great feeling when they tell you to “turn on your system” and that feeling continues as they provide all the documentation needed to complete your MEA grant application and SREC facilitation. The Enphase Enlighten phone app is also superb and you will always know how your system is operating at a moment’s notice. Celestial Solar Innovation is truly a top-notch, turnkey solar solution from the top and throughout, and we look forward to being a customer for years to come!

Their entire team was proficient and easy to work with. Celestial uninstalled and reinstalled solar panels that were originally put in by another solar company so we could repair our damaged roof. They were very flexible with scheduling with the other companies involved, especially with considerations of project points that needed to be completed before the next steps could proceed. "Plays well with others" and "proficient and efficient" are accurate descriptions of Celestial.

When we initially looked at getting solar panels we decided to research multiple companies. Over several weeks we looked into about 8 different companies ranging from smaller local companies to large national companies. We met with 5 of these companies and Celestial Solar was the final meeting. From our first meeting, it became very clear that Jim was the best fit for our needs. He was able to answer all of our questions and clearly explain the process and timeline. A key selling point was his explanation of the equipment he would be using as well as why he felt that it was the best. We had already done extensive research into the solar array business but we were still able to learn something new by talking to Jim. Jim also being local and very familiar with the permitting and inspection process was another reason we decided to move forward with him. We had multiple questions throughout the process and Jim took the time to provide thorough explanations. The entire process from the initial meeting to receiving Permission to Operate took just over 3 months. Throughout the whole process, we were constantly in communication with Jim receiving updates on the status of the job. The paperwork process was painless and relatively simple. The installation crew was able to complete the installation in 2 days. There were a few minor issues that popped up in the process but Jim was always available to remedy the situation. Once the job was completed Becky was able to assist us in providing paperwork for tax filings, MEA grant, warranty, and rebates along with providing information to set up our monitoring app and SREC account. Overall we were very pleased with Celestial Solutions and would highly recommend them to anyone interested in investing in a solar array.

Their price point, expertise, and workmanship was unmatched...and we shopped around a good bit. I would highly recommend Celestial Solar is you're considering solar. We just got a $2 electric bill.

This is actually the first review I have ever posted for a company and am doing so because of how impressed I was with Jim and his Celestial team throughout the whole process of going solar. Before I committed to going solar, I did a lot of research before I even talked with and requested quotes from 4 separate companies (2 national and 2 local). Jim was by far the most upfront and honest and his recommendations and suggestions were consistent with the research I had previously done on the current technology, pricing, estimated production, etc. He ended up working multiple designs for me to maximize my production while not wasting money and panels on roof locations that would not generate efficiently. His costs were substantially lower and the panel and microinverter selections were state of the art compared to the proposals the other companies were trying to convince me to go with. I am so happy I have gone solar and that I went with Jim and Celestial.

I couldn't be happier with my decision to work with Celestial! I spent way too much time trying to familiarize myself with solar hardware so I could confirm which of the many quotes I got was the best value when I could have just trusted the reviews. Celestial has been extremely diligent in their work and helpful with all my questions. They made the process as quick and easy as I could have imagined while providing incredible value with their industry-leading hardware. Now that I can see the impact it's making on my electric bill, I can say with certainty that they were the right choice!

Celestial Solar did a great job with my solar installation. Jim was helpful in my free consultation, answering all my questions and providing a couple great options for my array configuration. The installation team was fast and friendly. They knew I was scared that my dogs might get loose when they were coming and going, and they took great care to knock when entering and having me hold the dogs when leaving. The array has been running for a couple months now and is already making a huge difference in my electric bill. The team at Celestial has been so great with their follow-ups, between getting me set up to monitor production to setting me up to trade solar credits and everything else I've needed. They're knowledgeable, friendly, and professional - you can't go wrong with Celestial.

When I started researching which solar company to use, I had 4 companies provide bids. 3 of those companies were big chains that were quoting me for systems significantly too big, didn't understand local ordinances, and promising me things they could just not deliver. Celestial Solar, however, came in and explained everything to me very clearly right from the start. They were not the least expensive, but they provided me the best financing options, sent me ALL of the details on their products before our first meeting, provided a dozen customer testimonials (which none of the others did), and went above and beyond communicating to me throughout the entire process. It was a no -brainer when it came for who to choose and I 100% recommend them for your solar install.

Celestial Solar did an excellent job installing solar panels on our house in August 2023. We did a lot of research into various companies and Celestial Solar was an easy selection. Jim Reilly was great to work with. He explained everything (cost, process, benefits), answered all of our questions quickly and thoroughly, which made the decision very easy. Absolutely recommend them.

Jim and Celestial Solar were responsive, professional, and did great work. I wouldn't hesitate to recommend them to anyone. Their quote was accurate and no-nonsense. Timelines were accurate. Months after the install, they resolved a warranty repair on my solar combiner and were just as responsive. One of the best companies I've ever hired to do work on my home.

I did a lot of research, received several quotes and Celestial provided the best price. Jim Reilly was always quick to respond to my questions and helped with all the paperwork to get me all the rebates that I was qualified to receive. The installation only took one day and the installers were very professional and also quite personable. Overall the entire experience from beginning to end was so easy and really did exceed all my expectations. Couldn’t be happier!

We got multiple quotes and Celestial were the most knowledgeable and best price with an amazingly custom built system! I had a few companies ignore me and only talk to my husband - which was super condescending seeing as I'm the one who wanted to go solar and knew the ins and outs of everything. Jim had a great quote package showing that he knows exactly what the customer needs to see. He was also always a phone call or email away - usually answering you within 24 hours. The install was quick and although there are a lot of components to going solar, he walks you through all of them. I love our system and my electric bill this month was 6$ - since I have an electric car, I was ecstatic!

We had a terrific experience putting solar on our house with Celestial Solar Innovations, based in Frederick, MD. From the start, the process was clear, open and supportive of our needs. The company did first rate work in installing 35 panels on our home where we wanted them and where they knew they'd work best. They cared for the aesthetic as well as the production in the design. They recommended a roofing company as we needed to upgrade. Their communications about the process, cost and timing were excellent and frequent. When we wanted to paint the conduit the color of our roof, they even delivered it in advance of our panel installation so we could get that done. We would highly recommend Celestial Solar Innovations--and going solar!

After talking with a number of solar panel installers, we decided to go with Celestial Solar Innovations, a local Frederick County family owned company. We are extremely happy with our choice. Jim Reilly, the owner, is knowledgeable, experienced and helpful. He was very communicative about what was involved and carefully guided us through the whole process including getting the solar rebate. His crew was efficient and professional. The project was completed in September. Since then our solar gain has covered our electrical needs plus additional gain adding credit to our bill.

We recently completed a major remodel of our 1950's home with the last step being the design and installation of a solar panel array. We contacted several providers and, based in part on the recommendation of a neighbor, decided to work with Jim Reilly and Celestial. We couldn't be happier with the entire experience. Jim discussed our objectives with us and developed a preliminary design. We have a multi-story roof and had specific ideas on where to place panels for aesthetics. Jim and his engineering team worked with us to maximize our production while staying true to our design objectives. Installation was completed right on schedule and the system has been in production for several months. Our generation has met or exceeded the design specs to date. Jim also helped us to apply for the MD state Clean Energy Rebate, which has already been approved. He also provided the necessary information for setting up our SREC trading account and we have already received our first reimbursement. Our entire experience with Jim and Celestial Solar Innovations has been wonderful and I highly recommend you consider them if you are contemplating the addition of solar to your home or business.

I highly recommend Celestial Solar Innovations. I first learned about them on "Nextdoor". Jim Reilly, the owner, is a really nice guy who is easy to work with. My system has been running flawlessly since being installed 2 months ago. The only problem I'm having is with the utility company, who doesn't appear to be recording my usage data since installing the net meter. However, the app for my panels shows electricity production and net import/export power to the grid. At least I have a way to monitor it, while the utility company get's its act together.

I met with 4 solar companies for pricing. Celestial Solar won my business hands down. I knew from the minute I met Jim that he was the one. As a senior citizen, I felt very comfortable with him. It is clear he knows the solar business. Others I met with were quite scary and clearly had no idea how to set up solar on my property. I found Jim to be very honest. In fact, we talked about additional panels but after the site visit Jim didn’t think the return on investment for the additional panels was worth the added cost. The installation crew was awesome. Extremely respectful of both my property and me and they greeted me with smiles and encouraged questions each time I came out of the house to check on them. They were very well organized, great teamwork and knew their stuff. It’s been about a month since go-live and everything is working according to plan. I love that they do the paperwork, and the app which is part of the deal, is easy to use and tells you a lot about how your system is working. Great, great experience and I have nothing but awesome things to say about Celestial Solar. Jim is honest and all about customer service. I know I picked the right guy!
